摘要：
The oxidation of isopropyl, benzyl, and n-butyl alcohols to the corresponding aldehydes with tetramethylammonium fluorochromate was studied by spectrophotometry in acetonitrile solutions in the presence of p-toluenesulfonic acid. The reaction kinetics was studied under pseudo-first-order conditions with respect to the oxidizing agent. The Michaelis-Menten kinetics with respect to the substrate was observed, indicating the quasi-equilibrium formation of an oxidizing agent-alcohol complex. The formation constants and the rates of disproportionation of the complexes were determined. The temperature dependences of the reaction rates were studied, and the activation parameters were computed. A reaction scheme consistent with the observed results was proposed.
